Recently I bought the DE0-Nano-SoC Kit/Atlas-SoC development board from Terasic which contains a Cyclone V SoC from Altera. The board is a good starting point to get involved in embedded system development with SoCs. The Cyclone V SoC is a…

A new project is online: A frequency generator from theoretically 0.37 GHz to 3.740 GHz output frequency. It is based on the LTC6946-1 from Linear Technology, an Ultralow Noise 0.37 GHz to 3.740 GHz Integer N Synthesizer with Integrated VCO.…

This project is a design of a low frequency Variable Gain Amplifier which is intended to be used for amplitude adjustment in order, to for example use the full dynamic range of an ADC. The project came up when experimenting…

This project is about using the Microchip PIC18F13K50 MCU as a USB-serial controller, read out the MAX6675 temperature sensor and write some output on a LCD display. It came up to gain experience with the PIC18 MCU and see how…

A while ago I discovered that I own a PICkit2, which I had bought a while ago when I started to study microprocessors. With MPLabX Microchip has a IDE which runs under Linux, so I gave the kit a second…

This project came up to test PCB design with KiCAD. Some Atmel SAM3X8E microprocessors were available, the same as one finds on the Arduino Due, and I got tired on the limitations of the free version of Eagle. So I…

This is a follow up on the previews article on the low and high pass filter designer. An algorithm is developed in order to perform interpolation. The FIR low pass filter from the last post is used in the interpolation…
